Duct Cleaning Griffith, IN

Over the last two decades, improvements in energy conservation science have resulted in the construction of buildings with tight perimeters and minimal air leakage. While modern homes and offices are far more efficient, undesirable particulate matter can become trapped indoors, aggravating respiratory conditions and reducing HVAC efficiency.

Normal daily activities generate a substantial quantity of indoor contaminants, including human and animal dander, dust, pollen and debris. These pollutants are recycled through the heating and air conditioning system an average of 5-7 times a day. Even with effective filtration, the interior surface of the ductwork, air handler and evaporator coil can become coated with a sticky layer of unhealthy grime. This condition provides nutrients for a variety of undesirable biological organisms and degrades indoor air quality.

The Cleaning Process

Duct cleaning is a process that involves removing contaminants from a variety of critical heating and cooling components, including the supply and return air ducts, registers, heat exchanger, condensate pan, air handler, coils, motors and housings.

Upon entering the building, the technician will create an access point into the interior of the ductwork to conduct a visual inspection of the system. This is typically accomplished by using a hand held mirror, direct view periscope or a video camera. After determining the best approach for maximum effectiveness, the tech will seal off the air duct system, usually by apply a special tape over the supply registers and the return air grilles.

Using a specially designed high-pressure vacuum, the system is placed under significant negative pressure. After extracting the loose surface dirt, the technician will activate a mechanical brush or compressed air whip to dislodge any particulate matter that remains adhered to the surface of the ductwork. If mold or fungi is present, a biocide and sealant can be applied to the interior surface of the sheet metal to kill any remaining live organisms and prevent the establishment of future colonies.


In general, homeowners are usually attentive to the maintenance and service requirements of their heating and cooling equipment. However, the air distribution component in an HVAC system is often neglected until it causes an equipment related problem. Regular, routine duct cleaning provides several important benefits designed to reduce overall costs and maximize comfort.

  • Improved Indoor Air Quality (IAQ): Several studies have determined that an average six-room home will accumulate over 40 pounds of dust per year. This is a normal process that results from the breakdown of fibers in certain materials. Neglected duct systems are a perfect breeding ground for mold, bacteria and other biological organisms that convert dust and moisture into nutrients for growth.
  • Reduced Energy Costs: Accumulated dust, dirt and grime can substantially degrade HVAC system performance. Dirty coils diminish energy transfer efficiency, and clogged or obstructed ductwork can increase friction loss and restrict air flow.
  • Extend Equipment Life: A substantial number of equipment failures can be attributed to excessive dust, dirt and grime in an HVAC system. If left unaddressed, debris inside the air handler and air distribution network can reduce airflow by as much as 50 percent. This forces the other components in the system to work harder and longer to satisfy the indoor load, which ultimately reduces the equipment’s operational lifecycle.

Important IAQ Considerations

As part of a compressive IAQ strategy, duct cleaning can play an important role in keeping the indoor environment comfortable and healthy. The professionals at Meyer’s invite you to learn more about the features and benefits of their indoor air quality products and services.
